First of all, be sure to read Our tech report on the Flame/Flamer/TheFlame/sKyWIper Malware.
As You already know, some Microsoft certificates were abused for flame malware MiTM installation method.
But take a look on the technical details of the certificate chain.
The actual code is signed by a series of certificates:
One interesting thing is that the program file was timestamped, too:
Ok, let’s see the certificates from top to down:
